Description

A kind of automobile-used skidring

Technical field

The utility model relates to a kind of automobile-used skidring.

Background technology

In the higher area of some latitudes, car transported anti-skidding problem and continued to use anti-skidding tape always and be wrapped on the tire and solve winter.This non-skid feature is installed, dismounting is wasted time and energy, the top car is obvious during vehicle ', running velocity slow, road pavement and tire injury are very big, and skidring is difficult for fixation, often takes off chain, becomes flexible and even fall the chain situation.The Chinese patent CN2709222Y of on July 13rd, 2005 bulletin promptly discloses a kind of combined type automobile rubber antiskid band, and this skidring is to be hinged to a skidring to some with the suitable anti-skidding tongue piece of tire outline by crab shape butt hook to be sheathed on the tire periphery.This skidring is because the existence in gap between tongue piece and the tongue piece, top car performance is fairly obvious during driving, tyre slip is easy to cause the tongue piece hinge portion to lose efficacy and then the injury tire on soft ground, and because tongue piece still is confined to very little area with contacting of face of ice, friction force does not obtain big raising, the anti-skidding problem of not basic solution.

Summary of the invention

The purpose of this utility model provides a kind of, folding dress convenient, reliable automobile-used skidring big with contact area of ground.

The technical solution of the utility model is such: a kind of automobile-used skidring, comprising the skidring that is coated on the tire periphery and being used to strut skidring makes it contact the bracing frame that contacts into face with ground, support frame as described above is located in the inboard of tire central axis the following stated skidring, described skidring is to be formed by the outer compounded rubber of nylon tape, and described skidring 21 head and the tail two ends hinges connect.

Above-mentioned automobile-used skidring, described skidring has lateral surface that contacts with ground and the medial surface that contacts with tire, described skidring surfaces externally and internally is provided with anti-skidding oblique stria, the anti-skidding oblique stria of described skidring outside face communicates with the outside, the inboard both sides of institute's skidring respectively are provided with row's guide ledges, and described guide ledges is equally spaced along the inboard both sides of skidring.

Above-mentioned automobile-used skidring, support frame as described above comprise armature assembly, after poppet assembly and connect armature assembly and after poppet assembly and lay respectively at two strut bars compositions of tire lateral surface and medial surface.

Above-mentioned automobile-used skidring, described armature assembly comprises that front frame reaches the front jockey wheel of being located at rotationally on the described front frame, the prelocalization wheel that is higher than rotationally on the front frame reaches the preceding pinch roller of being located at rotationally on the front frame, and described front jockey wheel, the axis of prelocalization wheel and preceding pinch roller is parallel with tire axle, the axial both ends of the surface of described front jockey wheel are between described two guide ledges, described prelocalization wheel periphery face contacts with the tire circumference lateral surface, and described preceding pinch roller is taken turns coaxial setting with prelocalization and laid respectively at the outside of skidring medial surface two row's guide ledges.

Above-mentioned automobile-used skidring, described front frame also are provided with pinch roller before two relatively turnable pairs, pinch roller and preceding wheel pressing shaft line parallel and contact with anti-slide plate medial surface outside two guide ledges respectively before the described pair.

Above-mentioned car has skidring, described after poppet assembly comprises that after poppet reaches the back track adjusting wheel of being located at rotationally on the described after poppet and reaches the back locating wheel of being located at rotationally on the after poppet, and the axis of described back track adjusting wheel and back locating wheel is parallel with tire axle, between described two row's guide ledges, described back locating wheel periphery face contacts with the tire circumference lateral surface described back guide wheel shaft to both ends of the surface.

The end of described front jockey wheel and back track adjusting wheel is hemispherical, described prelocalization wheel two ends are provided with anti-projection partially, the anti-projection partially of described prelocalization wheel is inboard to be contacted with the front jockey wheel curved surface, locating wheel two ends, described back are provided with anti-projection partially, and the anti-projection partially of described back locating wheel is inboard to be contacted with back track adjusting wheel curved surface.Described front frame is provided with clip wheel, and described after poppet is provided with clip wheel, prevents that wheel face from scraping bracing frame.

Above-mentioned automobile-used skidring, described after poppet also are provided with two relatively turnable back pinch rollers, described back pinch roller and back locating wheel parallel axes and contact with skidring medial surfaces outside two row's guide ledges respectively.

Described front support rod and back support rod adjacent part are provided with a clasp, described back support rod and front support rod adjacent part are provided with a jack that matches with the clasp size, jack the inner is provided with catching groove, and by cooperating of described clasp and catching groove, described front support rod and back support rod are linked to be one.

Above-mentioned automobile-used skidring is provided with the tightening device that is used to adjust the skidring radial tension between described front support rod and the back support rod.

Tradition skidring and tire is owing to be that static state cooperates, friction force between skidring and the ground will be passed to tire by contacting between skidring and the tire, but the relative fixed between skidring itself and the tire is poor, skidring itself is easy to damage and destroys road surface and tire simultaneously like this, skidring is to contact with tire in the utility model, promptly in the wheel traveling process, skidring moves with respect to tire, skidring and ground are plane contact, this is similar to and lays a crawler belt that constantly extends on the running orbit of wheel, relative static and plane contact between this crawler belt and the ground, only the utility model is constantly the no crawler belt in back to be continued to deliver to the place ahead to go to carry out recycle, thereby big spoke degree improves the friction coefficient between tire and the ground and grabs the ground ability, because skidring is static with respect to ground, it does not damage road surface and tire.In addition, the installation and removal of skidring for convenience, but the utility model is provided with the connecting device and the tightening device of repeated removal at two strut bars, and very convenient to use.
